Campaign Mode: players work through one of four different environments busting ghosts to earn cash and upgrade their equipment. 12 maps across 4 themed environments:

Library

Streets

Cemetery

Museum

Okay, so the campaign mode is really just a mini-campaign, but it sounds like the environments are quite large, and each time you play through, you gain experience points toward your profile rank. This rank helps determine the difficulty settings each time you play, and can also serve as a matchmaking tool should you want to play Ghostbusters as a "competitive co-op" game.
